Illuminating the recently completed and extensive
refurbishments to St Peter’s Square in Rome, are
modern and energy-efficient outdoor LED lumi-
naires which provide an outstanding lighting expe-
rience and an energy saving of approximately 70
percent.The project concept by
Direzione dei Servizi
Tecnici del Governatorato dello Stato della Città del
Vaticano
was realised with support from Osram.
Cooperationwith
ServiziTecnici del Governatorato
was also fundamental to the success of the Sistine
Chapel project, carried out in 2014. The new light-
ing system for the Sistine Chapel featured higher
lumen-output and artwork-conserving LED lighting
to protect and enhance Michelangelo's renowned
frescoes. It also served as a lighting benchmark for
artistic, historical and preservation projects.
"We gained worldwide recognition for our state-
of-the-art LED lighting of the Sistine Chapel, and
we're exceedingly pleased to have demonstrated
in Rome once again our strength as a provider of
complex lighting solutions with the illumination
of St Peter's Square," said Olaf Berlien, CEO of
OSRAM Licht AG.
As with the Sistine Chapel project, the lighting
solution for St Peter's Square was planned and put
into operation through close cooperation between
Osram and the
Direzione dei Servizi Tecnici del
Governatorato SCV
. "In addition to ideal lighting
results, the task included visual aspects such
as the discreet integration of luminaires into the
architectural setting and incorporating a simple,
unobtrusive electrical installation. Saving energy and
ecological sustainability were also important," said
Eladia Pulido, CEO of the Osram Lighting Solutions
(LS) business unit.
TheVatican specified an illuminance level of up to
120 lux at night to provide safety for visitors and to
enable reading on the square during events and cele-
brations. One hundred and thirty two LED floodlights
were installed, providing sufficient brightness and
homogeneous illumination for the square. The new
lighting lends the existing architecture and materials
a visual upgrade – the light underlines the impressive
columnar architecture and emphasises the innate
colour of the marble. Ecological sustainability was
simultaneously addressed, and for this reason the
lighting concept focused on cutting power consump-
tion and avoiding unwanted light emission. "Thanks
to modern LED technology in combination with a
DALI light management system we have achieved
energy savings of around 70%," said Carlo Bogani,
Executive Project Director at Osram Italy.
The 132 LED luminaires installed are a customer-
specific version of the Floodlight 20 LED with
through-wiring and special plug connections that
enable simple installation and easy inter-wiring of
the luminaires. The luminaires are equipped with
a DALI Professional control system and feature a
4000 K light colour (neutral white).
St Peter's Square (
Piazza San Pietro
in Italian),
located directly in front of St Peter's Basilica in
Rome, consists of a trapezoid section and the actual
elliptical forecourt with a total area of 48 000 m
2
. Up
to 400 000 people gather on the extensive square
for celebrations and special occasions, such as the
election of a new Pope or at Easter time. Extensive
renovation of St Peter's Square began in 2011, and
at the beginning of the current year Osram together
with
Direzione dei ServiziTecnici del Governatorato
SCV
created the new lighting concept based on
modern LED technology that was installed and
inaugurated in the evening on October 20, 2016.
